Étude de performance de la régénération du dernier cycle du catalyseur au niveau de raffinage d'Arzew

Abstract

Catalytic reforming is a chemical process used to convert a portion of petroleum, known as "heavy naphtha", into high-quality gasoline. During this process, the catalyst gradually loses its activity due to the buildup of coke, which is a carbon deposit. Over time, this accumulation leads to the deactivation of the catalyst. To prevent this deactivation, a regeneration process is carried out to remove the carbon deposits and restore the catalyst's original activity and performance. In this study, we evaluated the performance of the catalytic reforming unit at the Arzew refinery, specifically comparing the reforming section's efficiency before and after regeneration, and assessing the feasibility of regeneration to enhance gasoline quality, particularly by improving the octane number. The studied catalyst is of the UOP R-86 type, a high-performance catalyst for catalytic reforming.
